Application Insights: The Tool You Never Knew You Needed
summary
Application Insights instruments apps with or without code, shows live metrics and CPU profiling, and captures exceptions plus the SQL queries that caused them so developers get decompiled line numbers and locals for each failure. It sends flattened JSON (retains interactive data for two years) and costs about $0.50/GB at scale after a free trial range. Examples shown: an Angular + ASP.NET Core Tour of Heroes and a SharePoint “YouTube for the enterprise” that both report user events and errors. codeless instrumentation snapshot debugger live metric stream
